Roll one or multiple d20s for D&D and TRPG with quick count presets.
Use cases
- Resolve D&D and TRPG ability checks, saving throws, and attack rolls.
- Roll multiple d20s for group checks, initiative variants, or random tables.
- Compare multiple visible d20 results or add them for group checks.
Choose 1d20, 2d20, 4d20, or 20d20
Use the quick buttons to set the number of twenty-sided dice. One d20 is the standard check; larger batches help when several characters roll at once or when a table needs repeated d20 results.
- 1d20: one standard ability check, saving throw, or attack roll.
- 2d20: two separate visible results for comparison.
- 4d20 and 20d20: fast batches for groups, simulations, and random tables.
Visible results and totals
Every requested d20 remains visible, and the total shows their sum. Use the individual values for separate checks or compare them according to your game rules.
Every roll runs locally in your browser using crypto.getRandomValues. No account or server-side roll history is required.
How to use
